A Full-Dive type VRMMO swept the world with its unique system that follows an "infinitely" varied pattern of evolution. "Black Raven" Juliet reigns fourth in the duel ranking of the Kingdom of Altar, one of the nations in it. She is a shy person and reserved in real life, but actually she is just a junior high school student who loves gothic and only speaks chuuni language in on a regular basis. Today too, Juliet utilizes her sword skill and Fallen Knight job skills to go on an adventure with her only friend, Chelsea.
